The serial communication ports utilize the Modbus protocol, unless configured for DNP operation (see descriptions below).
This allows the EnerVista UR Setup software to be used. The UR operates as a Modbus slave device only. When using
Modbus protocol on the RS232 port, the M60 responds regardless of the MODBUS SLAVE ADDRESS programmed. For the
RS485 port, each M60 must have a unique address from 1 to 254. Address 0 is the broadcast address which all Modbus
slave devices listen to. Addresses do not have to be sequential, but no two devices can have the same address or conflicts
resulting in errors will occur. Generally, each device added to the link should use the next higher address starting at 1. See
Appendix B for more information on the Modbus protocol.
A value of 0 closes the port. When the Modbus port is set to 0, communicate with the relay using the front panel or serial
port.
When a 0 value is involved in a change, the changes to the MODBUS TCP PORT NUMBER setting take effect
when the M60 is restarted.
h) PROTOCOL
Select among DNP3.0, IEC60870-104, and IEC60870-103, with DNP being the default. For any change to take effect,
restart the unit.
The table captures all possible combinations of protocols.
